FERTILIZER-DIST'RIBUTER.

SPECIFICATION forming part of Letters Patent No. 570,490, dated November3, 1896. Application iiled J'une 20, 1896. Serial No. 596,385. (Nomodel.)

To all whom it may concern.-

Be it known that I, EDWIN D. MEAD, a citizen of the United States,residing at Phelps,

in the county of Ontario and State of New York, have invented certainnew and useful Improvements in Fertilizer-Distributers, of which thefollowing is a specification.

My invention relates to fertilizer-distributers, the presentconstruction being designed primarily as an improvement upon theconstruction set forth in Letters Patent No. 265,529, which were grantedto me on the 3d day of October, 1882.

One object of the present invention is to so construct the device as tosimplify the assembling of the parts and consequently to render moreeasy the operation of taking the sower apart.

A further object of the invention is to provide means whereby leakageand consequent waste of material is prevented.

Other novel features are embodied in the present structure and will befully set forth in the following speciiication, reference being had tothe annexed drawings, in which- Figure l is a top plan View of thedistributer; Fig. 2, a vertical sectional view on the line l l, Fig. l;Fig. 3, a perspective of the various parts shown in a separatedrelation, and Fig. 4 is a bottom plan view of so much of the structureas is necessary to show certain details of construction.

Referring to said drawings, A indicates the hopper, and B a plate orcasting secured to the lower part thereof, and from which eX- tends thefeed-cup C, said cup being provided with a discharge-outlet D.

E indicates the rotating disk or feed-wheel seated in a specific mannerwithin the lower part of the cup C, as will be hereinafter set forth. Itis provided on its lower face with a series of gear-teeth adapted tomesh with a pinion F, said pinion receiving its motion from a shaft G,connected with the drivingwheel of the machine.

The feed-wheelE is formed on its periphery with an undercut recess orseat a. Fitting around this seat, and between it and the side face andprojecting ledge b of the cup C, is a packing ring or band H. This bandwill be preferably formed of brass and as shown in4 Y the drawings; thatis, it will occupy the space formed between the feed-wheel and the cup,its ends projecting through an opening c in the side of the cup, firmlyholding it in place and in its proper relation to the other parts.Instead of employing brass as the material of which to form the packingother substances may be employed, for instance, any other metal,leather, rubber, or any textile substance. The principal object is toemploy some material which will prevent leakage of the fertilizer frombetween the parts. The feed-wheel is provided with a central openingwhich registers with an openingd, formed in a spider-arm I, whichextends across the bottom of cup C and beneath the feed-wheel. Therecess CZ is of two diameters, the lower reduced portion being formedwith two sockets or seats e e, while the under face of the spider at oneside of said recess is slightly cut away or rounded, as shown in Fig. 2.

J indicates the cranked axle, its lower arm K being formed to nt withinthe opening d, and having studs or lugs f f, adapted to be seated in thesockets e e when the parts are assembled. Extending from the lower endof the arm is a hook or finger L. That portion of the arm K opposite thehook is slightly rounded, which permits of the arm being worked downinto the recess d, and allows the hook or :finger to engage the underface of the spider. No direct pull will separate the parts, but they maybe readily dismantled when it becomes necessary so to do. It will benoted that this construction does away with all bolts or loose partswhich would be liable to come loose by thev continued vibrau tion of themachine.

M indicates the clearer or scraper wheel, mounted uponthe upright stud Nof the crank K. It is formed with a series of openings or slots g in itslower edge, which engage with teeth 7L, formed upon 'the upper face ofthe feed-wheel O at or near its periphery. The central portion of thescraper-wheel, which receives the stud N, is continued above said stud,'and within its upper end is seated a bolt t, to which is secured thestirrer O.

A shield or guard P is secured over the scraper or clearer wheel and isof such form as to effectually prevent the escape of the material aroundthe wheel. It also permits of a better or more advantageous location ofIOO the gate Q with relation to the dischargespout in that the gate maybe placed at a greater distance from the spout and the spout made largerand left free from all obstruction. The shield or guard is formed withan opening j, designed to embrace the upright projection of thescraper-wheel before the stirrer O is secured in place. It is alsoprovided with a downwardly-projecting portion 7c, designed to close thespace between the feed-cup and the scraper-wheel on the side oppositethe gate. An upturned lip Z is provided, against which the gate Q bears.It is of such height that no matter what may be the adjustment of thegate the lip will prevent the material from finding its way around thegate at this point. To properly hold the guard in place, it is formedwith a downwardly-projecting flange m, which in turn is provided withtwo lugs or toes fn.. A downwardly-projecting stud 0 is formed at theforward right-hand side of the guard. The toes take` in recesses oropenings p p, formed in the plate B, and the stud o in an opening q. Itwill be seen upon reference to Figs. 2 and 3 that the guard is curvedslightly upward along its upper face near the rear, and this is toprovide for the shaft R, upon which the gate Q is mounted. This curvedportion tends to hold the shaft in its proper position. The outer end ofthe shaft is provided with the usual index finger or arm and is joui'-naled in one side of the frame or hopper to which the index-plate isattached, its inner end resting upon a seat T, formed upon the plate B.The shaft being square and the opening in the gate through which itpasses being of like form the gate must of necessityT turn with saidshaft.

The lower end of the gate is of such form as to fit down over thefeed-wheel and between the cup and clearer or scraper wheel, while theupper portion of the gate closes the space between the side wall of thehopper and the lip Z of shield or guard I".

The gate is shown closed in dotted lines in Fig. 2, and when in suchposition approximately all exit from the hopper is cut off. By raisingthe gate more or less the desired quantity of material maybe fed out,but there is no leakage between any of the parts.

Under some conditions it may be found desirable to interpose a wedge, asS, between the flange m of guard P and the wall of the hopper. Thiswedge securely holds and prevents the parts from displacement while inuse, but may be easily and readily withdrawn when it is desired to takethe machine apart.

In assembling the device the upright projection of wheel M is passedthrough the opening j and the stirrer secured in place. Then once thisis done, it need not be removed except for replacement of broken or wornparts. The shaft and pinion being in place, the bushing or packing Hissecured within the cup, after which the feed-wheel is put in place.

rlhe arm K of the crank .I is

then passed through the opening in the feedwheel, the studs or lugs jentering the recess c e and the finger L taking under the spiderframe.This prevents the crank from turning and secures the parts in theirproper position. Next the scraper-wheel and guard I) are put in place,thelugs n entering the openings Ap and the stud 0 the opening q, thescraper-wheel in the meantime fitting down over the axle N. Finally thewedge S is put in place.

In the operation of the device the gate is adjusted to the proper pointand motion is imparted to the shaft G. Thence it is transmitted to thefeed-wheel through the pinion and from the feed-wheel to thescraper-wheel and the stirrer, the direction of rotation being indicatedin Fig. l by arrows.
